P.R. Laws tit. 27, § 1251
(a) All hearings before the Commission shall be public. Hearings, investigations or other proceedings by the Commission shall be governed by the provisions of § 1260 of this title and such rules as the Commission may prescribe. The parties may appear before the Commission by themselves or assisted by counsel.
(b) No person shall be excused from testifying or from producing any books, documents or other evidence in any investigation or hearing before the Commission, when ordered to do so, on the ground that it may incriminate him or may put him in jeopardy of penalty or forfeiture of any legal right. But no person who has invoked his right against self-incrimination shall be prosecuted, punished or subjected to any penalty or forfeiture of any legal right by reason or on account of any matter regarding which he is compelled to testify or to produce documentary or other evidence. No person so testifying shall, however, be exempt from prosecution or punishment for perjury committed in so testifying.
